Femia: Army War College finds serious risks to military from climate change

Last week, the Federal News Network’s “Federal Drive” ran an interview with the IMCCS’s Senior Advisor and Manager, Francesco Femia, regarding a recent U.S. Army War College report that alarmingly found the U.S. military “precariously underprepared for the national security implications of climate change-induced global security challenges.” Femia highlighted the key takeaways from the report, including an extraordinary finding specific to the Army, which stated that the service “precipitously close to mission failure concerning hydration of the force in contested arid environments.” Femia recommended that both technical, as well as big strategic and operational changes and investments, are needed to prepare the Army, and the broader U.S. military, for this rapidly-changing operational landscape – including to prepare for the likelihood of adversaries taking advantage of these changes, and a lack of U.S. leadership for addressing them.

Briefer: Climate Change Implications for Military Aircraft

By Mariah Furtek

Climate change is radically altering the physical environment in the theater of conflict, making future military successes dependent on adaptation today. New research shows that climate change is reducing performance of U.S. military aircraft. As the environment grows hotter and more humid, military aircraft will not be able to carry as much payload or travel long distances without refueling. More missions will be cancelled or modified due to decreased aircraft performance on hot and humid days, which diminishes the U.S. military’s ability to project power and respond effectively to conflicts.

Changes in the operational environment require corresponding changes in infrastructure, logistics, and acquisitions. To be effective long-term, these modifications must be informed by data-driven analysis of climate projections.

The adverse impacts of climate change on military-readiness are especially evident in aircraft and airbases. As heat and humidity rise, aircraft struggle to perform: meaning today’s inventory might not be fit to operate in tomorrow’s conflict. Anticipating the strain that climate change places on current inventory will help make current operations and infrastructure more resilient to climate threats. To this end, U.S. military and military stakeholders would benefit from a vulnerability assessment model that predicts the frequency and severity of climate-related performance impacts for both airbases and aircraft.

This Center for Climate and Security Briefer explores one such model developed by Air Force Colonel Mary McRae (ret.). McRae’s model translates future climate projections from Global Climate Models into Density Altitude (DA) measurements that communicate specific changes in aircraft performance influenced by heat and humidity. Using this DA approach, McRae maps the vulnerability of various airbases and aircraft to DA conditions that limit the viability of future operations.[1] This vulnerability assessment tool will help military, policy and industry constituents determine the most critical threats to aircraft and airbase operations; effectively mitigate climate threats through more informed military acquisitions, infrastructure and mission planning.

More accurate and detailed climate threat assessments like McRae’s make critical threats to military-readiness more visible. In doing so, updated vulnerability assessments enable current acquisitions processes to take climate change into account. These assessments also help the acquisitions community inform industry stakeholders about climate threats and ensure that infrastructure in development today is being designed in a climate-conscious manner. The information these assessments provide also encourages research into innovative design solutions that can adapt existing infrastructure to fit more challenging environments.

New U.S. Army War College Report Urges Action on Climate Change

By Mariah Furtek

The United States Army War College recently released a report exploring the significant impact climate change will have on national security and U.S. Army operations, and offering a set of urgent recommendations. The second sentence of the report sets the stage immediately, stating “the Department of Defense is precariously underprepared for the national security implications of climate change-induced global security challenges.” 

The report details the most eminent threats climate change poses to national security: severe weather events, mass migration, diminishing global freshwater supplies, changing disease vectors, Arctic competition, stress on the U.S. power grid and nuclear reactors, as well as sea-level rise. 

In addition to addressing these broader climate security risks, the authors focus on the U.S. Army and highlight how diminished freshwater supplies jeopardize existing hydration practices. Currently, the Army relies heavily on bottled water and local wells in the theater of operation to hydrate troops when they are deployed. The Army lacks in-house hydration capacity: the Brigade Combat Teams, for example, have not been able to support their own water needs since 2015. 

Reliance on external sources for water poses a serious threat to Army mobility and capacity. This threat expands as environments around the world grow even hotter, increasing troops’ demand for water. As stated by the authors, “The US Army is precipitously close to mission failure concerning hydration of the force in contested arid environments.” To mitigate this risk, the report recommends the Army explore advanced technologies that capture ambient humidity and recycle water for reuse.

At the pole, melting ice in the Arctic is opening a new zone of competition over Arctic transit routes and natural resources. The report argues that the Army must improve training and equipment to prepare for an expanded role in the Arctic. To highlight the importance of U.S. Army investment in Arctic operations, the authors draw attention to Russia’s ongoing renovation of its Soviet-era Arctic bases and expansion of its “Arctic Army.”

The report also highlights how the Army will be called on to respond to domestic and foreign infectious disease outbreaks due to its unique proficiency operating in challenging environments. The Army must prepare for an increase in frequency and intensity of these disease outbreaks as changing disease vectors and a warmer, more humid climate amplify tickborne diseases and malaria. 

The authors advise the Army to prepare for future restrictions on fuel use by running simulations using virtual and augmented reality.  

Finally, the report recommends that the Army engage proactively in climate change-oriented campaign planning to anticipate future climate conflicts and mass migration in countries like Bangladesh. Incorporating future challenges into today’s budgets will distribute the cost of adaptation. 

Climate change is radically altering the theater of operations and the homefront, increasing the challenges the U.S. military faces at each stage of its national security mission. This report echoes the need to more fully incorporate climate threats into our security awareness and military readiness.

The New U.S. Department of Defense Leadership Team on Climate Security

By John Conger

As the confirmation processes continue for both Mark Esper to become U.S. Secretary of Defense and General Mark A. Milley to become U.S. Chairman of the Joint Chiefs of Staff, it is worth exploring what these officials have said and done about climate security in general, or particular aspects of it, while they’ve been in their current positions running the Army – including most recently during the confirmation process.

First, as Secretary of the Army, Dr. Esper submitted to Congress a top ten list of his most climate-vulnerable bases, focusing mostly on drought and desertification, and committed to “work closely with other leaders throughout the Department of Defense and with Congress to identify corrective actions and implement steps to enhance our readiness and capability in the face of climate related threats.”

In addition, as both Esper and Milley testified before the House Armed Services Committee on April 2, 2019, Congressman Langevin asked them to comment on the impact that climate change has on military readiness.

Secretary Esper responded: “I’m not sure that I could say that it poses a threat to our readiness, but climate change is something we have to take into account as we consider our installations, our training ranges and how and where we may fight in the future.”

General Milley replied: “I would say the effects of climate change are things we have to consider at the strategic, operational, and tactical level and all of our military operations in the future.”

Finally, both Secretary Esper and General Milley responded to Advance Policy Questions from the Senate Armed Services Committee in advance of their confirmation hearings.  Each of them was asked to comment on the readiness and resource impacts of extreme weather.

Secretary Esper’s responses (pasted in full below) generally accepted the premise that extreme weather had a readiness impact and agreed that it was prudent to pursue resiliency at U.S. military bases.

General Milley’s answers to the Advance Policy Questions (also pasted in full below) provided more detail, noting the challenge posed by the cost of recovery from extreme weather events and the readiness disruptions during the recovery period while infrastructure is being rebuilt and critical facilities are unavailable.

When asked about improving the resiliency of U.S. military bases, he stated: “DoD faces a long-term threat from extreme weather events, rising sea levels, and increased flooding at coastal locations. If confirmed, I will work with DoD’s many stake holders in support of ongoing DoD actions to implement appropriate planning and design standards that account for projected sea level rise and extreme weather events.”

Secretary Esper and General Milley joint a long list of at least 30 senior defense officials, during this Administration, that have highlighted the security risks of a changing climate, and the need to do something about it.

1. Advance Policy Questions and Answers: Secretary Esper

Readiness and Resource Impacts from Extreme Weather

In 2017, three hurricanes resulted in over $1.3 billion in damage to military installations across the U.S. In 2018, extreme weather events caused roughly $9 billion in damage at Tyndall Air Force Base, Camp Lejeune, and Offutt Air Force Base. Hurricane season for 2019 already has begun.

How would you assess the readiness and resource impacts on DOD from recent extreme weather events?

        Secretary Esper: From my previous experience as the Army Secretary, severe weather events have had an impact on DoD’s ability to conduct training and operations at certain installations. It has been my experience that DoD assesses resilience holistically throughout the installation planning and basing processes. If confirmed, I would work with DoD leadership to ensure our planning considers extreme weather events.

Based on these readiness and resource impacts, do you believe it necessary to use more resilient designs in DOD infrastructure?

       Secretary Esper:  I do believe having more resilient designs for our facilities and infrastructure is prudent.

2. Advance Policy Questions and Answers: General Milley

Readiness and Resource Impacts from Extreme Weather

In 2017, three hurricanes resulted in over $1.3 billion in damage to military installations across the U.S. In 2018, extreme weather events caused roughly $9 billion in damage at Tyndall Air Force Base, Camp Lejeune, and Offutt Air Force Base. Hurricane season for 2019 already has begun.

How would you assess the readiness and resource impacts on DoD from recent extreme weather events?

General Milley: The impacts are significant. Over $10 billion in two years creates a strain on our finite resources and forces us to make tough decisions if not supplemented with additional funding. Beyond the nominal cost, damages to infrastructure and delayed repairs also disrupted flight and ground training. It will take time to correct these training backlogs.

Based on these readiness and resource impacts, do you believe it necessary to use more resilient designs in DoD infrastructure?

General Milley: DoD faces a long-term threat from extreme weather events, rising sea levels, and increased flooding at coastal locations. If confirmed, I will work with DoD’s many stake holders in support of ongoing DoD actions to implement appropriate planning and design standards that account for projected sea level rise and extreme weather events.
